1.    General:

Tactical Diversified Futures Fund L.P. (the “Partnership”) is a limited partnership organized under the partnership laws of the State of New York on December 3, 2002 to engage, directly or indirectly, in the speculative trading of a diversified portfolio of commodity interests including futures contracts, options, swaps and forward contracts. The sectors traded include currencies, energy, grains, indices, U.S. and non-U.S. interest rates, livestock, lumber, metals and softs. The commodity interests that are traded by the Partnership directly and through its investments in the Funds (as defined in Note 5 “Investment in Funds”) are volatile and involve a high degree of market risk.

Between March 27, 2003 (commencement of the public offering period) and April 30, 2003, 36,616 redeemable units of limited partnership interest (“Redeemable Units”) were publicly offered at $1,000 per Redeemable Unit. The proceeds of the initial public offering were held in an escrow account until April 30, 2003, at which time they were turned over to the Partnership for trading. The Partnership was authorized to publicly offer 300,000 Redeemable Units during the initial public offering period. As of December 4, 2003, the Partnership was authorized to publicly offer an additional 700,000 Redeemable Units. As of October 7, 2004, the Partnership was authorized to publicly offer an additional 1,000,000 Redeemable Units. As of June 30, 2005, the Partnership was authorized to publicly offer the 2,000,000 Redeemable Units previously registered. The public offering of Redeemable Units terminated on November 30, 2008. The Partnership currently privately and continuously offers Redeemable Units to qualified investors. There is no maximum number of Redeemable Units that may be sold by the Partnership.

Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the “General Partner”) and commodity pool operator of the Partnership. The General Partner is wholly owned by Morgan Stanley Smith Barney Holdings LLC (“MSSB Holdings”). Morgan Stanley, indirectly through various subsidiaries, owns a majority equity interest in MSSB Holdings as well as Morgan Stanley & Co. LLC, a commodity broker for the Partnership (“MS&Co.”). Citigroup Inc. indirectly owns a minority equity interest in MSSB Holdings. Citigroup Inc. also indirectly owns Citigroup Global Markets Inc. (“CGM”), the commodity broker and a selling agent for the Partnership. Morgan Stanley expects to purchase, subject to regulatory approvals, Citigroup Inc.’s remaining interest in MSSB Holdings. Prior to July 31, 2009, the date as of which MSSB Holdings became its owner, the General Partner was wholly owned by Citigroup Financial Products Inc., a wholly owned subsidiary of Citigroup Global Markets Holdings Inc., the sole owner of which is Citigroup Inc.

As of March 31, 2013, all trading decisions are made for the Partnership by Drury Capital, Inc., (“Drury”), Graham Capital Management, L.P., (“Graham”), Willowbridge Associates Inc. (“Willowbridge”), Aspect Capital Limited (“Aspect”), Krom River Trading AG and Krom River Investment Management (Cayman) Limited (collectively, “Krom River”), Altis Partners (Jersey) Limited (“Altis”), Boronia Capital Pty. Ltd. (“Boronia”) and Kaiser Trading Group Pty. Ltd. (“Kaiser”) (each an “Advisor” and collectively, the “Advisors”), each of which is a registered commodity trading advisor or exempt from registration. Each Advisor is allocated a portion of the Partnership’s assets to manage. The Partnership invests the portion of its assets allocated to each of the Advisors indirectly through investments in the Funds.

The General Partner and each limited partner share in the profits and losses of the Partnership in proportion to the amount of Partnership interest owned by each except that no limited partner shall be liable for obligations of the Partnership in excess of its capital contribution and profits or losses, if any, net of distributions.

The accompanying financial statements and accompanying notes are unaudited but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the Partnership’s financial condition at March 31, 2013 and December 31, 2012, and the results of its operations and changes in partners’ capital for the three months ended March 31, 2013 and 2012. These financial statements present the results of interim periods and do not include all disclosures normally provided in annual financial statements. You should read these financial statements together with the financial statements and notes included in the Partnership’s annual report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) for the year ended December 31, 2012.

The preparation of financial statements and accompanying notes in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and related disclosures of contingent assets and liabilities in the financial statements and accompanying notes. As a result, actual results could differ from these estimates.

Due to the nature of commodity trading, the results of operations for the interim periods presented should not be considered indicative of the results that may be expected for the entire year.

2.    Financial Highlights:

Changes in the net asset value per unit for the three months ended March 31, 2013 and 2012 were as follows:

The above ratios may vary for individual investors based on the timing of capital transactions during the period. Additionally, these ratios are calculated for the limited partner class using the limited partners’ share of income, expenses and average net assets.

3.    Trading Activities:

The Partnership was formed for the purpose of trading contracts in a variety of commodity interests, including derivative financial instruments and derivative commodity instruments. However, the Partnership’s investments are in other funds. The results of the Partnership’s trading activities resulting from its investments in the Funds are shown in the Statements of Income and Expenses and Changes in Partners’ Capital.

The customer agreements between the Partnership/Funds and CGM or MS&Co., as applicable, give the Partnership and the Funds the legal right to net unrealized gains and losses on open futures contracts and open forward contracts. The Partnership and the Funds net, for financial reporting purposes, the unrealized gains and losses on open futures and open forward contracts on the Statements of Financial Condition as the criteria under Accounting Standards Codification (“ASC”) 201-20, “Balance Sheet,” have been met.

All of the commodity interests owned by the Partnership are held for trading purposes.

Brokerage fees are calculated as a percentage of the Partnership’s adjusted net asset value on the last day of each month and are affected by trading performance, subscriptions and redemptions.

On January 1, 2013, the Partnership adopted Accounting Standards Update (“ASU”) 2011-11, “Disclosure about Offsetting Assets and Liabilities” and ASU 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities”. ASU 2011-11 created a new disclosure requirement about the nature of an entity’s rights to setoff and the related arrangements associated with its financial instruments and derivative instruments, while ASU 2013-01 clarified the types of instruments and transactions that are subject to the offsetting disclosure requirements established by ASU 2011-11. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of these disclosures is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards (“IFRS”). The new guidance did not have a significant impact on the Partnership’s financial statements.

4.    Fair Value Measurements:

Partnership’s and the Funds’ Investments. All commodity interests, including derivative financial instruments and derivative commodity instruments, are held for trading purposes. The commodity interests are recorded on trade date and open contracts are recorded at fair value (as described below) at the measurement date. Investments in commodity interests denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing at the measurement date. Gains or losses are realized when contracts are liquidated. Unrealized gains or losses on open contracts are included as a component of equity in trading account on the Statements of Financial Condition. Net realized gains or losses and any change in net unrealized gains or losses from the preceding period are reported in the Statements of Income and Expenses and Changes in Partners’ Capital.

Partnership’s and the Funds’ Fair Value Measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety. Management has concluded that based on available information in the marketplace, the Funds’ Level 1 assets and liabilities are actively traded.

GAAP also requires the use of judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Partnership’s and the Funds’ Level 2 assets and liabilities.

The Partnership and the Funds will separately present purchases, sales, issuances and settlements in their reconciliation of Level 3 fair value measurements (i.e., to present such items on a gross basis rather than on a net basis), and make disclosures regarding the level of disaggregation and the inputs and valuation techniques used to measure fair value for measurements that fall within either Level 2 or Level 3 of the fair value hierarchy as required under GAAP.

On October 1, 2012, the Financial Accounting Standards Board (“FASB”) issued ASU 2012-04 “Technical Corrections and Improvements,” which makes minor technical corrections and clarifications to Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures”. When the FASB issued Statement 157 (codified in ASC 820), it conformed the use of the term “fair value” in certain pre-Codification standards but not others. ASU 2012-04 conforms the term’s use throughout the ASC “to fully reflect the fair value measurement and disclosure requirements” of ASC 820. ASU 2012-04 also amends the requirements that must be met for an investment company to qualify for the exemption from presenting a statement of cash flows. Specifically, it eliminates the requirements that substantially all of an entity’s investments be carried at “market value” and that the investments be highly liquid. Instead, it requires substantially all of the entity’s investments to be carried at “fair value” and classified as Level 1 or Level 2 measurements under ASC 820. The amendments are effective for fiscal periods beginning after December 15, 2012. The adoption of this ASU did not have a material impact on the Partnership’s financial statements.

The Partnership and the Funds consider prices for exchange-traded commodity futures, forwards and options contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forwards, swaps and certain options contracts for which market quotations are not readily available are priced by broker-dealers who derive fair values for those assets and liabilities from observable inputs (Level 2). Investments in funds (other commodity pools) with no rights or obligations inherent within the ownership interest held by the Partnership are priced based on the end of the day net asset value (Level 2). The value of the Partnership’s investments in the Funds reflects its proportional interest in the Funds. As of and for the periods ended March 31, 2013 and December 31, 2012, the Partnership and the Funds did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). For the three months ended March 31, 2013 and the year ended December 31, 2012, there were no transfers of assets and liabilities between Level 1 and Level 2.

The General Partner is not aware of any material changes to the trading programs discussed above during the fiscal quarter ended March 31, 2013.

Aspect Master’s, Drury Master’s, Willowbridge Master’s, Graham Master’s, Altis Master’s, KR Master’s, Boronia I, LLC’s and Kaiser I, LLC’s (collectively, the “Funds”) trading of futures, forwards and options contracts, if applicable, on commodities is done primarily on U.S. commodity exchanges and foreign commodity exchanges. The Funds (other than Boronia I, LLC and Kaiser I, LLC) engage in such trading through commodity brokerage accounts maintained with CGM, while Boronia I, LLC and Kaiser I, LLC engage in trading through commodity brokerage accounts maintained with MS&Co.

A limited partner of the Funds may withdraw all or part of their capital contribution and undistributed profits, if any, from the Funds as of the end of any day. Such withdrawals are classified as a liability when the limited partner elects to redeem and informs the Funds.

Management and incentive fees are charged at the Partnership level, with the exception of Boronia I, LLC and Kaiser I, LLC (collectively the “Trading Companies”), where the Partnership paid, indirectly, its pro rata portion of the management and incentive fees of the Trading Companies. All exchange, clearing, service, user, give-up, floor brokerage and National Futures Association fees (collectively the “clearing fees”) are borne by the Partnership directly and through its investment in the Funds. All other fees, including CGM’s direct brokerage fees, are charged at the Partnership level except for the brokerage fees paid to MS&Co., which will be paid indirectly by the Partnership.

At March 31, 2013, the Partnership owned approximately 82.7% of Drury Master, 48.6% of Willowbridge Master, 71.8% of Aspect Master, 48.5% of Graham Master, 83.3% of KR Master, 75.7% of Altis Master, 55.3% of Boronia I, LLC and 55.5% of Kaiser I, LLC. At December 31, 2012, the Partnership owned approximately 85.4% of Drury Master, 77.3% of Willowbridge Master, 72.1% of Aspect Master, 74.7% of CFM Master (prior to its redemption on December 31, 2012), 57.8% of Graham Master, 81.8% of KR Master and 75.6% of Altis Master. It is the Partnership’s intention to continue to invest in the Funds. The performance of the Partnership is directly affected by the performance of the Funds. Expenses to investors as a result of investment in the Funds are approximately the same and the redemption rights are not affected.

6.    Financial Instrument Risks:

In the normal course of business, the Partnership, through its investments in the Funds, is a party to financial instruments with off-balance sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include forwards, futures, options and swaps, whose values are based upon an underlying asset, index or reference rate, and generally represent future commitments to exchange currencies or cash balances, to purchase or sell other financial instruments on specific terms at specified future dates, or, in the case of derivative commodity instruments, to have a reasonable possibility to be settled in cash, through physical delivery or with another financial instrument. These instruments may be traded on an exchange or over-the-counter (“OTC”). Exchange-traded instruments are standardized and include futures and certain forwards and option contracts. OTC contracts are negotiated between contracting parties and include swaps and certain forward and option contracts. Specific market movements of commodities or futures contracts underlying an option cannot accurately be predicted. Each of these instruments is subject to various risks similar to those related to the underlying financial instruments, including market and credit risk. In general, the risks associated with OTC contracts are greater than those associated with exchange-traded instruments because of the greater risk of default by the counterparty to an OTC contract. The General Partner estimates that at any given time approximately 11.8% to 27.9% of the Partnership’s/Funds’ contracts are traded OTC.

The risk to the limited partners that have purchased Redeemable Units is limited to the amount of their share of the Partnership’s assets and undistributed profits. This limited liability is a result of the organization of the Partnership as a limited partnership under New York law.

Market risk is the potential for changes in the value of the financial instruments traded by the Partnership/Funds due to market changes, including interest and foreign exchange rate movements and fluctuations in commodity or security prices. Market risk is directly impacted by the volatility and liquidity in the markets in which the related underlying assets are traded. The Partnership/Funds are exposed to a market risk equal to the value of futures and forward contracts purchased and unlimited liability on such contracts sold short.

Credit risk is the possibility that a loss may occur due to the failure of a counterparty to perform according to the terms of a contract. The Partnership’s/Funds’ risk of loss in the event of a counterparty default is typically limited to the amounts recognized in the Statements of Financial Condition and is not represented by the contract or notional amounts of the instruments. The Partnership’s/Funds’ risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership/Funds to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership/Funds have credit risk and concentration risk as MS&Co., CGM or a CGM affiliate is the sole counterparty or broker with respect to the Partnership’s/Funds’ asset. Credit risk with respect to exchange-traded instruments is reduced to the extent that through MS&Co. or CGM, the Partnership’s/Funds’ counterparty is an exchange or clearing organization.

As both a buyer and seller of options, the Funds pay or receive a premium at the outset and then bear the risk of unfavorable changes in the price of the contract underlying the option. Written options expose the Funds to potentially unlimited liability; for purchased options, the risk of loss is limited to the premiums paid. Certain written put options permit cash settlement and do not require the option holder to own the reference asset. The Funds do not consider these contracts to be guarantees.

The General Partner/Managing Member monitors and attempts to control the Partnership’s/Funds’ risk exposure on a daily basis through financial, credit and risk management monitoring systems, and accordingly, believes that it has effective procedures for evaluating and limiting the credit and market risks to which the Partnership/Funds may be subject. These monitoring systems generally allow the General Partner/Managing Member to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures, forwards and options positions by sector, margin requirements, gain and loss transactions and collateral positions.

The majority of these financial instruments mature within one year of the inception date. However, due to the nature of the Partnership’s/Funds’ businesses, these instruments may not be held to maturity.

7.    Critical Accounting Policies:

Use of Estimates. The preparation of financial statements and accompanying notes in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and related disclosures of contingent assets and liabilities in the financial statements and accompanying notes. As a result, actual results could differ from these estimates.

Partnership’s and the Funds’ Investments. All commodity interests held by the Funds, including derivative financial instruments and derivative commodity instruments, are held for trading purposes. The commodity interests are recorded on trade date and open contracts are recorded at fair value (as described below) at the measurement date. Investments in commodity interests denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing at the measurement date. Gains or losses are realized when contracts are liquidated. Unrealized gains or losses on open contracts are included as a component of equity in trading account on the Statements of Financial Condition. Net realized gains or losses and any change in net unrealized gains or losses from the preceding period are reported in the Statements of Income and Expenses.

Partnership’s and the Funds’ Fair Value Measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety. Management has concluded that based on available information in the marketplace, the Funds’ Level 1 assets and liabilities are actively traded.

GAAP also requires the use of judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Partnership’s and the Funds’ Level 2 assets and liabilities.

The Partnership and the Funds will separately present purchases, sales, issuances, and settlements in their reconciliation of Level 3 fair value measurements (i.e., to present such items on a gross basis rather than on a net basis), and make disclosures regarding the level of disaggregation and the inputs and valuation techniques used to measure fair value for measurements that fall within either Level 2 or Level 3 of the fair value hierarchy as required under GAAP.

The Partnership and the Funds consider prices for exchange-traded commodity futures, forwards and options contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forwards, swaps and certain options contracts for which market quotations are not readily available are priced by broker-dealers who derive fair values for those assets and liabilities from observable inputs (Level 2). Investments in funds (other commodity pools) with no rights or obligations inherent within the ownership interest held by the Partnership are priced based on the end of the day net asset value (Level 2). The value of the Partnership’s investments in the Funds reflects its proportional interest in the Funds. As of and for the periods ended March 31, 2013 and December 31, 2012, the Partnership and the Funds did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). For the three months ended March 31, 2013 and the year ended December 31, 2012, there were no transfers of assets and liabilities between Level 1 and Level 2.

Futures Contracts. The Funds trade futures contracts. A futures contract is a firm commitment to buy or sell a specified quantity of investments, currency or a standardized amount of a deliverable grade commodity, at a specified price on a specified future date, unless the contract is closed before the delivery date or if the delivery quantity is something where physical delivery cannot occur (such as the S&P 500 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Funds each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Funds. When the contract is closed, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in futures contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the futures broker, directly with the exchange on which the contracts are traded. Net realized gains (losses) and changes in net unrealized gains (losses) on futures contracts are included in the Statements of Income and Expenses.

Forward Foreign Currency Contracts. Forward foreign currency contracts are those contracts where the Funds agree to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. Forward foreign currency contracts are valued daily, and the Funds’ net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in the Statements of Financial Condition. Net realized gains (losses) and changes in net unrealized gains (losses) on forward foreign currency contracts are recognized in the period in which the contract is closed or the changes occur, respectively, and are included in the Statements of Income and Expenses.

The Funds do not isolate that portion of the results of operations arising from the effect of changes in foreign exchange rates on investments from fluctuations from changes in market prices of investments held. Such fluctuations are included in net gain (loss) on investments in the Statements of Income and Expenses.

London Metals Exchange Forward Contracts. Metal contracts traded on the London Metals Exchange (“LME”) represent a firm commitment to buy or sell a specified quantity of aluminum, copper, lead, nickel, tin or zinc. LME contracts traded by the Funds are cash settled based on prompt dates published by the LME. Payments (“variation margin”) may be made or received by the Funds each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Funds. A contract is considered offset when all long positions have been matched with a like number of short positions settling on the same prompt date. When the contract is closed at the prompt date, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in LME contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the broker, directly with the LME. Net realized gains (losses) and changes in net unrealized gains (losses) on metal contracts are included in the Statements of Income and Expenses.

Options. The Funds may purchase and write (sell) both exchange listed and OTC options on commodities or financial instruments. An option is a contract allowing, but not requiring, its holder to buy (call) or sell (put) a specific or standard commodity or financial instrument at a specified price during a specified time period. The option premium is the total price paid or received for the option contract. When the Funds write an option, the premium received is recorded as a liability in the Statements of Financial Condition and marked to market daily. When the Funds purchase an option, the premium paid is recorded as an asset in the Statements of Financial Condition and marked to market daily. Net realized gains (losses) and changes in net unrealized gains (losses) on options contracts are included in the Statements of Income and Expenses.

Income Taxes. Income taxes have not been provided as each partner is individually liable for the taxes, if any, on its share of the Partnership’s income and expenses.

GAAP provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements and requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Partnership’s financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the Partnership level not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current year. The General Partner concluded that no provision for income tax is required in the Partnership’s financial statements.

The Partnership files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The 2009 through 2012 tax years remain subject to examination by U.S. federal and most state tax authorities. The General Partner does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Subsequent Events. The General Partner evaluates events that occur after the balance sheet date but before financial statements are filed. The General Partner has assessed the subsequent events through the date of filing and determined that there were no subsequent events requiring adjustment of or disclosure in the financial statements.

Recent Accounting Pronouncements. In October 2011, the FASB issued a proposed ASU intended to improve and converge financial reporting by setting forth consistent criteria for determining whether an entity is an investment company. Under longstanding GAAP, investment companies carry all of their investments at fair value, even if they hold a controlling interest in another company. The primary changes being proposed by the FASB relate to which entities would be considered investment companies as well as certain disclosure and presentation requirements. In addition to the changes to the criteria for determining whether an entity is an investment company, the FASB also proposes that an investment company consolidate another investment company if it holds a controlling financial interest in the entity. In August 2012, the FASB updated the proposed ASU to state that entities regulated under the Investment Company Act of 1940 should qualify to be investment companies within the proposed investment company guidance. The Partnership will evaluate the impact that this proposed update would have on the financial statements once the pronouncement is issued.

Net Income (Loss) per Unit. Net income (loss) per unit is calculated in accordance with investment company guidance. See Note 2, “Financial Highlights”.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Liquidity and Capital Resources

The Partnership does not engage in the sale of goods or services. Its only assets are its investment in Funds and cash. The Funds’ only assets are their equity in trading accounts, consisting of cash and cash margin, net unrealized appreciation on open futures contracts, net unrealized appreciation on forward contracts and commodity options, if applicable, and interest receivable. Because of the low margin deposits normally required in commodity futures trading, relatively small price movements may result in substantial losses to the Partnership, through its investments in the Funds. While substantial losses could lead to a material decrease in liquidity, no such illiquidity occurred during the first quarter of 2013.

The Partnership’s capital consists of the capital contributions of the partners as increased or decreased by gains or losses on trading and by subscriptions, expenses, interest income, redemptions of Redeemable Units and distributions of profits, if any.

For the three months ended March 31, 2013, Partnership capital decreased 4.6% from $488,182,538 to $465,559,831. This decrease was attributable to the redemptions of 31,473.1710 Redeemable Units resulting in an outflow of $29,511,595, and the redemptions of 539.000 General Partner unit equivalents totaling $500,418, which was partially offset by the subscriptions of 3,031.3150 Redeemable Units totaling $2,838,453, coupled with the net income of $4,550,853. Future redemptions could impact the amount of funds available for investment in commodity contract positions in subsequent periods.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Management believes that the estimates and assumptions utilized in preparing the financial statements are reasonable. Actual results could differ from those estimates. The Partnership’s significant accounting policies are described in detail in Note 7 of the Financial Statements.

The Partnership records all investments at fair value in its financial statements, with changes in fair value reported as a component of net realized gains (losses) and change in net unrealized gains (losses) in the Statements of Income and Expenses and Changes in Partners’ Capital.

Results of Operations

During the first quarter of 2013, the Partnership’s net asset value per unit increased 0.9% from $927.41 to $935.97 as compared to a decrease of 2.2% in the same period of 2012. The Partnership experienced a net trading gain before brokerage fees and related fees in the first quarter of 2013 of $14,290,858. Gains were primarily attributable to the Funds’ trading in currencies, livestock, metals, softs and indices and were partially offset by losses in energy, grains and U.S. and non-U.S. interest rates. The Partnership experienced a net trading loss before brokerage fees and related fees in the first quarter of 2012 of $1,182,457. Losses were primarily attributable to the Partnership/Funds’ trading in currencies, grains, U.S. and non-U.S. interest rates, livestock, metals and softs and were partially offset by gains in energy and indices.

The most significant gains were recorded within the global stock index markets during January from long positions in U.S., Pacific Rim, and European equity index futures as prices moved higher after German business confidence improved, economic reports in the U.S. and China beat estimates, and a weaker yen boosted Japan’s exports. Within the currency markets, gains were achieved primarily during January from short positions in the Japanese yen versus the U.S. dollar, Canadian dollar, euro, and Australian dollar as the value of the yen declined on speculation the Bank of Japan will ease monetary policy further. Additional currency gains were experienced during March from long positions in the Mexican peso versus the U.S. dollar as the value of the peso moved higher after a gain in U.S. retail sales boosted the outlook for Mexican exports. Within the metals sector, gains were experienced primarily during March from short positions in copper futures as prices fell after a key gauge of Chinese manufacturing missed estimates, spurring concern metals demand may slow. Within the agricultural sector, gains were experienced primarily during March from short positions in coffee futures as prices declined, heading for the longest slump since August, on signs of slowing demand for beans from Brazil, the world’s top coffee producer.

A portion of the Partnership’s gains for the quarter was offset by losses incurred within the energy sector during February from long futures positions in crude oil and its related products as prices fell sharply following news that the U.S. economy grew less than economists expected and manufacturing expanded less than forecast in China and contracted in Europe. Losses were also incurred within the global interest rate sector, primarily during January, from long positions in U.S. and European fixed income futures as prices fell amid positive economic reports and after European Central Bank President Mario Draghi said the euro-area economy should gradually recover this year.

Commodity futures markets are highly volatile. The potential for broad and rapid price fluctuations increases the risks involved in commodity trading, but also increases the possibility of profit. The profitability of the Partnership/Funds depends on the existence of major price trends and the ability of the Advisors to correctly identify those price trends. Price trends are influenced by, among other things, changing supply and demand relationships, weather, governmental, agricultural, commercial and trade programs and policies, national and international political and economic events and changes in interest rates. To the extent that market trends exist and the Advisors are able to identify them, the Partnership expects to increase capital through operations.

Interest income on 80% of the average daily equity maintained in cash in the Partnership’s (or the Partnership’s allocable portion of a Fund’s, other than Boronia I, LLC and Kaiser I, LLC) brokerage account was earned at a 30-day U.S. Treasury bill yield determined weekly by CGM based on the average non-competitive yield on 3-month U.S. Treasury bills maturing in 30 days. MS&Co. credits Boronia I, LLC and Kaiser I, LLC on 100% of the average daily equity maintained in cash in the account of Boronia I, LLC or Kaiser I, LLC during each month at the rate equal to the monthly average of the 4-week U.S. Treasury bill discount less 0.15% during such month. Interest income for the three months ended March 31, 2013 decreased by $3,717 as compared to the corresponding period in 2012. The decrease in interest income is primarily due to lower average daily equity maintained in the Partnership’s account during the three months ended March 31, 2013, as compared to the corresponding period in 2012. Interest earned by the Partnership will increase the net asset value of the Partnership. The amount of interest income earned by the Partnership depends on the average daily equity in the Partnership’s and the Funds’ accounts and upon interest rates over which neither the Partnership/the Funds nor CGM/MS&Co. has control.

23

Brokerage fees are calculated as a percentage of the Partnership’s adjusted net asset value on the last day of each month and are affected by trading performance, subscriptions and redemptions. Accordingly, they must be compared in relation to the fluctuations in the monthly net asset values. Brokerage fees for the three months ended March 31, 2013 decreased $2,390,314, as compared to the corresponding period in 2012. The decrease in brokerage fees is due to a decrease in average net assets for the three months ended March 31, 2013, as compared to the corresponding period in 2012.

Management fees are calculated as a percentage of the Partnership’s adjusted net asset value as of the end of each month and are affected by trading performance, subscriptions and redemptions. Accordingly, they must be compared in relation to the fluctuations in the monthly net asset values. Management fees for the three months ended March 31, 2013 decreased $921,824, as compared to the corresponding period in 2012. The decrease in management fees is due to a decrease in average net assets for the three months ended March 31, 2013, as compared to the corresponding period in 2012.

Incentive fees are based on the new trading profits generated by each Advisor at the end of the quarter as defined in the respective management agreements between the Partnership, the General Partner and each Advisor. Trading performance for the three months ended March 31, 2013 resulted in incentive fees of $77,475. There were no incentive fees earned for the three months ended March 31, 2012. To the extent an Advisor incurs a loss for the Partnership, the Advisor will not be paid incentive fees until such Advisor recovers any net loss incurred by the Advisor and earns additional new trading profits for the Partnership.

In allocating the assets of the Partnership among the Advisors, the General Partner considers past performance, trading style, volatility of markets traded and fee requirements. The General Partner may modify or terminate the allocation of assets among the Advisors and may allocate assets to additional advisors at any time.

As of March 31, 2013 and December 31, 2012, the Partnership’s assets were allocated among the trading Advisors in the following approximate percentages:

Item 3.   Quantitative and Qualitative Disclosures about Market Risk

The Partnership/Funds are speculative commodity pools. The market sensitive instruments held by them are acquired for speculative trading purposes, and all or substantially all of the Partnership’s/Funds’ assets are subject to the risk of trading loss. Unlike an operating company, the risk of market sensitive instruments is integral, not incidental, to the Partnership’s main line of business.

The limited partners will not be liable for losses exceeding the current net asset value of their investment.

Market movements result in frequent changes in the fair value of the Partnership’s/Funds’ open positions and, consequently, in their earnings and cash balances. The Partnership’s/Funds’ market risk is influenced by a wide variety of factors, including the level and volatility of interest rates, exchange rates, equity price levels, the market value of financial instruments and contracts, the diversification effects among the Partnership’s/Funds’ open contracts and the liquidity of the markets in which they trade.

The Partnership/Funds rapidly acquire and liquidate both long and short positions in a wide range of different markets. Consequently, it is not possible to predict how a particular future market scenario will affect performance, and the Partnership’s/Funds’ past performance is not necessarily indicative of their future results.

“Value at Risk” is a measure of the maximum amount which the Partnership/Funds could reasonably be expected to lose in a given market sector. However, the inherent uncertainty of the Partnership’s/Funds’ speculative trading and the recurrence in the markets traded by the Partnership/Funds of market movements far exceeding expectations could result in actual trading or non-trading losses far beyond the indicated Value at Risk or the Partnership’s/Funds’ experience to date (i.e., “risk of ruin”). In light of the foregoing as well as the risks and uncertainties intrinsic to all future projections, the inclusion of the quantification in this section should not be considered to constitute any assurance or representation that the Partnership’s/Funds’ losses in any market sector will be limited to Value at Risk or by the Partnership’s/Funds’ attempts to manage their market risk.

Exchange maintenance margin requirements have been used by the Partnership/Funds as the measure of their Value at Risk. Maintenance margin requirements are set by exchanges to equal or exceed the maximum losses reasonably expected to be incurred in the fair value of any given contract in 95%-99% of any one-day interval. The margin levels are established by dealers and exchanges using historical price studies as well as an assessment of current market volatility (including the implied volatility of the options on a given futures contract) and economic fundamentals to provide a probabilistic estimate of the maximum expected near-term one-day price fluctuation. Maintenance Margin has been used rather than the more generally available initial margin, because initial margin includes a credit risk component, which is not relevant to Value at Risk.

Value at Risk tables represent a probabilistic assessment of the risk of loss in market risk sensitive instruments. The Advisors currently trade the Partnership’s assets indirectly in master fund managed accounts over which they have been granted limited authority to make trading decisions. The first two trading Value at Risk tables reflects the market sensitive instruments held by the Partnership indirectly, through its investment in the Funds. The remaining trading Value at Risk tables reflect the market sensitive instruments, held by each Fund separately. There have been no material changes in the trading Value at Risk information previously disclosed in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2012.

The following tables indicate the trading Value at Risk associated with the Partnership’s open positions by market category as of March 31, 2013 and December 31, 2012. As of March 31, 2013, the Partnership’s total capitalization was $465,559,831.

As of December 31, 2012, the Partnership’s total capitalization was $488,182,538.

As of March 31, 2013, Drury Master’s total capitalization was $80,015,349. The Partnership owned approximately 82.7% of Drury Master. As of March 31, 2013, Drury Master’s Value at Risk for its assets (including the portion of the Partnership’s assets allocated to Drury for trading) was as follows:
